UNITE ERNST BANZHAF, OF EASTON, PENNSYLVANIA.

CHIMNEY.

T o all 'whom it may concern:

Be it known that 1, ERNST Bimznar, a citizen of the United States, residing at Easton, in the county of Northampton and State of Pennsylvania, have invented certain new and useful Improvements in Chimneys; and` l do hereby declare the following to be a` full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in chimneys and means for securing a stove-pipe thereto.

It is an object of the invention to provide in combination with a chimney, novel means for holding a stove-pipe placed in communication with the flue of the chimney, said means also holding the stove-pipe against undue movement.

It is also an object of the invention to provide a novel holding means for a stove-pipe including two eecentrics rotatably mounted adapted to bind against a stove-pipe 'and effectually clamp the same.

Itis also an object of the invention to provide a novel device of this character which will be simple in construction, eflicient and advantageous in practice and con'iparatively inexpensive to manufacture.

With the above and other` objects in view, the invention consists of the details of construction and in the novel arrangement and combination of parts to be hereinafter more particularly referred to.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this specification wherein like characters of reference denote corresponding parts in the several views and in which,

Figure 1 is a perspective view showing a chimney with the present invention applied thereto. Fig. 2 is a cross sectional view of the chimney taken through the pipe holding means. Fig. 3 is a fragmentary longitudinal section of the chimney, the pipe holding means being shown in elevation. Fig. i1 is a view in front elevation of the pipe holding means detached. Fig. 5 is a view in rear elevation of the pipe holding means detached. Fig. 6 is a view in side elevation of the pipe holding means detached. Fig. 7 is a view in elevation of a detail of the invention, said de- Speecation of Letters Patent.

tail illustrating the eccentric clamping rings, and, Fig. S is a view in plan of one of the eccentric rings detached.

ln the drawings, 1 denotes the sections of a chimney having a central opening 2 which forms the flue of the chimney. rlhe opposed edges of the sections are provided with the interlocking lips or flanges 3 as is particularly shown in F ig. 3. Each of these sections 1 is formed of plastic material, preferably cement, and have arranged around the flue or opening 2 and parallel therewith the vents -1- which effectually prevent over-heating of the section. These vents are also provided for the purpose of carrying off gases or other odors within a room and in order that this function may be performed, one of the sections 1 within a room is provided in one of its faces with the transverse openings 5 which communicate with certain of said vents 4.

The chimney when assembled is surmounted with a cap (3 which is provided with an opening 7 registering with the flue Q and is further provided in one of its side faces with the lateral openings S which communicate with the vents 1 in communication with the openings 5 hereinbefore referred to.

One of the sections l and preferably that section provided with the openings 5 has formed therein a passage-way 9 which communicates with the flue 2 and projecting within this flue 2 is a thimble 10 for the reception of a stove-pipe section 11. Projecting outwardly or laterally from one end of the thimble 1() is a plurality of angularly formed brackets 1Q to which is suitably secured a shield 13 which is adapted to contact with the outer surface of the section 1 or other surface for limiting the inward movement of the thimble within the passage-way 9. The opposite end portion of the thimble 10 is coiled upon itself as at 14 to embrace a reinforcing wire 15. This wire 15 is provided with inwardly projecting loops 16 at the outer or open end of each of the bayonet slots 17 arranged at dian'xetrically opposed points in the thimble 10. These bayonet slots 17 act in conjunction with pins 1S suitably positioned in the wall of the passage 9. It is thought to be obvious from this ar rangement that the thimble may be effectually held within the passage 9. The loops 16 readily permit the passage of the pin 1S Within the bayonet slots and also actas abutments for limiting the inward movement ot the pipe section 11 when applied Within the thinible.

Between the brackets 12 and the shield 13 are mounted the rings 19 and 2O Which have their peripheries concentric but the edges of their openings eccentric one opposed With relation to the other. Each of the rings is further provided with a series of concentrically disposed openings 21. Certain of the openings of one ot the rings are adapted to register With the openings of the second ring. At a pre-determined point7 the shield 13 is provided with a segmental slot Q2 arranged in line with the openings 21 of the rings. ritter the pipe section 11 has been inserted Within the tliimble 10, a suitable tool is inserted Within registering openings in the rings 19 and 2O positioned in alinement With the segmental slot 21 and said rings are caused to rotate by this tool until the inner ring 20 is caused to bind against the pipe section 11. The tool is then sui'liciently Withdrawn until it engages only the opening in the outer section 19 when said section 19 is rotated in an opposite direction until it binds against the pipe section 11. By this arrangement it will be seen that the pipe section 11 will be etfectually held Within the thimble 10 and that suitable provision is made owing to the eccentric arrangementof the Walls of the openings of the rings to properly center the pipe section 11.

I claim:

1. Tn combination with a chimney having a passage in communication With its flue, of a thiinble insertible Within the passage, means for locking the thimble Within the passage, a shield carried by the outer end of the thimble and spaced therefrom, rings mounted between the outer end of the thimblc and the shield, said rings having eccentric bores, said rings being provided With in Aans for their rotation.

2. 1n combination With a chimney having a passage in communication With its flue, ot a thimble insertible Within the passage, said .thimble having at its inner end, bayonet slots, pins positioned Within the passage acting in conjunction With the bayonet slots for holding the thimble against displacement7 a reinforcing Wire arranged at the inner end ot' the thimble7 said reinforcing Wire being provided at the mouths of the bayonet slots with inwardly projecting loops.

1n testimony whereof T have signed my name to this specification in the presence of tiro subscribing Witnesses.
